5. fwgs_library_dependency -- downloads dependency from Web, unpacks it, calls find_library to configure and links to the target. Also does a cache check, if developer have deleted dependency folder for some reason. Just a big shortcut.

6. fwgs_add_compile_options -- like add_compile_options, but with language specification: C for C/C++ flags, CXX for C++ flags, CONLY for C only flags. Also should work with CMake 2.8, which is still used in Ubuntu 12.04, Debian 7 and Steam Runtime toolchain.
